Keyword(s):
foundout a critical corresponding relationship between a δwheelof any maximal simple plane graph of n vertices(nMSPG)and its corresponding δcycleof a corresponding n-1MSPGof the nMSPG, and relied on theinductive way, while with the help of KempeChain (KC), this article gives a brand-newlogical proof for the famous and morethan 100 years old fourcolor conjecture (4CC).
